Once in awhile a product, although not for sale, is simply too beautiful not to write about. The O-bow ($TBA) is an electronic musical instrument. Using a standard bow or even a wooden stick, changes in the midi are produced via an optical sensor which measures the bow speed and horizontal angle with high resolution. To play you will need a midi keyboard to produce the string sound and the O-bow would add the bow flavor. There is no word yet on whether this device will ever hit the market, but I’m hoping we will see a Kickstarter for it soon.
